SHEET MATERIAL. PACKAGE Filed June 3, 15154 United States Patent-O SHEET MATERIAL PACKAGE Znchris Enzio Mikael Nuorivaara, Overboelare-Gram` mont, Belgium, assignor to Svenska Tandsticks Aktiebolaget, Jonkoping, Sweden, a Swedish joint-stock company This invention relates to a package for sheet material and more especially to a shipping package for wallboards which, being relatively thin must have their edges protected against abrasion or impact, and being usually somewhat flexible Should be prevented from bending or breaking in handling and transport.

Various forms of packagings have been used for such wallboards, but they were not entirely successful, because they require a considerable space which increases the expense of freight charges, particularly when shipped. lron bands are usually tied around the package, but they are often damaged, especially as they easily catch in other articles and are often carelessly used as attaching points for hooks for dragging and raising the package.

It is an object of the present invention to provide a simple and inexpensive packaging for transport of wallboards which will give complete protection to the sheets and will occupy a minimum of space.

Another object is to protect the metal bands against being used as attaching points for hooks.

With the foregoing and other objects in View, which will become more fully apparent as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing and defined in the appended claims.

ln the drawing:

Figure l is a partial plan View of a package of wallboards according to one embodiment of the invention;

Figure 2 is a section along the line ll--H in Figure l, and

Figure 3 is a section along the line lll-lll in Figure 2.

wallboards are in the usual way packed for handling and transportation in packages made up of a number of boards placed in face-to-face relation so as to form a stack, as shown in the drawing and indicated by numeral 1. The edges of the wallboards rest against slightly thicker frame members by which they are protected. The frame members consist of two equally thick wooden laths 2, 3. Between the two centre wallboards, a number of metal bands 4 are inserted, the ends of which are fixed to the lower luth 3 by means of staples 5. The wallboards are held together by means of U-shaped holders 6 having two stamped-out portions 7, which go between the laths 2 and 3. The holders are also provided with reinforce` ments in the form of outwardly pressed channels 8. The laths 2 and 3 are joined together by means of nails 9 which also pass through the metal bands and can thus replace the staples. The nails may also be driven through the projecting parts '7 of the U-shaped holders. The edges of the frame may to advantage be held together by means of triangular plates 1li which are inserted between the two middle wallboards and the two halves of the frame members, and are held by means of nails passing through the frame members.

As shown by the drawing, the packaging according to the invention takes up only slightly more space than the wallboards in the direction perpendicular thereto, so that a considerable amount of loading space can be saved in comparison with former packaging. As the metal bands holding the frame `together are arranged between the wallboards, these are protected from damage from the outside.

A number of wallboards may be packed in the following manner. One half of the wallboards going into one package are stacked on top of one another on a table, after which metal bands and, if necessary, corner plates are placed in position on the uppermost sheet. The other half of the wallboards is then placed on the metal bands and corner plates, after which the holder 8 is fitted into the proper position. The lower laths 3 are then pressed into intimate contact with` the edges of the lower wallboards, after which the metal bands are nailed onto the laths 3. Finally lthe laths 2 are placed on the laths 3 and nailed.

As can be seen from the above, only one embodiment of the invention is illustrated, and various modifications are possible Within the framework of the invention.
